How many people would notice small waves cresting on Pacific seas, and steer for a hidden island?

On the straining embankments of Dongting lake - which is the size of Luxembourg - an army of one million peasants were mobilised to support the efforts of 115,000 troops as waves crested over the top of levies.

With winds so fierce you couldn't breathe, rain that felt like razors, and waves cresting over the boat, he was able to move the boat out from among the pilings, rocks, seawall and docks while the storm raged on, tying it off bow-to-sea.

Origin

Crest comes from Latin crista, meaning ‘a tuft or plume’. Crestfallen (late 16th century), meaning ‘dejected’, is an extension of its original use to describe an animal or bird with a drooping crest. Crease (late 16th century) is probably an alternative form of crest, the idea being that a fold in a length of cloth forms a ridge or crest.
